Please share and explain, that's the whole point of the forum.Apparently my case was that i couldn't pass the first third of the installer, setup couldn't read from Essentials.pkg and therefore OS X couldn't be installed on this computer.I redid the USB installer with another image thinking that the checksums were wrong, i deleted platfor.plist, tried different things but to no avail.To my last resort i simply repaired permissions of Essentials.pkg on the USB installer disk and it successfully finished this time around, writing this from DP1 So it was just a simple permissions thing that kept my install from completing, Cheers
